Crash upon launching (Fresh install)

Hey, well i have reinstalled steam because after like 1 year it’s started to get sticky.

Everything is fine hl2 starts normally so does CSS. Come to gmod and when I launch it it just has a white screen and ‘Stops Responding’. This is a fresh install, and have completely removed the gmod folder and reinstalled.

I have tried things for example ‘-dxlevel 81, -fullscreen, -windowed’ etc. and no luck. I don’t think it’s my Graphics drivers because they are newly updated and HL2 and CSS work with no problems. Yes it’s a legal copy (It’s on steam).

That’s all the questions I think you would ask on common :P.
